Description
Indicates a loss of power or blown fuse has occurred
Attempting to acquire HDSL2 synchronization with the H2TU-R
Normal operation; HDSL2 synchronization is achieved with the H2TU-R
DSX-1 signal is present and synchronized with no errors
No DSX-1 signal, or signal is present with errors
DS1 signal from CPE is present at H2TU-R with no errors
No DS1 signal from CPE at H2TU-R, or present with errors
Normal Operation; end-to-end HDSL2 synchronization good
Loss of end-to-end HDSL2 synchronization on the 2-wire Loop
GFI or overcurrent condition detected
HDSL2 synchronization has not been achieved on the 2-wire Loop
Normal operation; signal margin is optimum (6 dB) on the 2-wire Loop
Marginal operation; signal margin is 1-5 dB on the 2-wire Loop
Margin dB; severely impaired HDSL2 operation
If attenuation (LOSS on Current System Status Screen) is  30 dB the
solid. If attenuation is > 30 dB, the LED flashes green, yellow, or red as determined by
DSL
the signal quality
Normal operation; No HDSL2 CRC errors detected by this unit within the last 30 minutes
on the 2-wire Loop
One or more HDSL2 CRC errors are being detected by this unit on the 2-wire Loop
Four or more HDSL2 CRC errors have been detected on the 2-wire Loop within the last 30
minutes. The LED remains lit for 30 minutes. If no HDSL2 CRC errors occur within a 
rolling 30 minute interval, the LED extinguishes.
